To all whom it may concem; v

Beit lcnown that 1, JAMES Ross aacitizen of the United States, residing at LaporteQ in the county of-Laporte and Statejfoi": In--* 5 diana have invented a certain new and use.- f

ful- Improvement in Transmission Gases, of whichthe following is a specification.

This invention relates; to traction one-"- gines and particularly to the construction, of 10 transmission housing andcasing: for the, same. It. has for'one, object to proyidepatransmission; housing in which; the-' entire 5 rear axle transmission; assembly may hemade up complete while it is,- still separatefrom the rest of thetractiont engine, so that it maybe treated as aunit andthe-parts as, sembled and properly lined upiand theunit subsequentlyjoinedv to the forward pnrt t the transmission housing." It" has-for an other. object toprovide a construction where: in all ofthe moving: parts of the tiians'inission except the heel can becompletely e-nclosed" and be protected from dust. Other objects 'wi-ll;v appear fI'OllQ time te timethroughout the specification'a nd claims.

My' invention is illustrated more on. less diagrammatically in, the accompanying} drawings;wherein-: .v v q f t igure 1 is'a' SiClGBIE-VfltlOIlrOf a tractor t with the rear axle assembly; in, positionto be connected to forward par't oi"? housing; 1'

"The"l.1S6i and 5 opemtionoi' this invention, are-asfoilQWs-z 1 The; rear; half of tthe: transmission caseis assembled: with: Jthe; aide housings and the bearings which they'carry, The stun shaftsare complete the parts are as shownv inFigure 1. The rear end of the forward transmission case may be supported by jack or any suitable manner and L-l'l9ll the entire rear axle unit is rolled forward into position. The pairs of laterally extending flanges on the transmission case are bolted together and the axle housings are screwed to the forward half of: chetransmission case and the assembly is'co'mplete;

For the purpose of repair and inspection the parts may be separated in obvious manner and by means of the construction of this invention the origina'lassembly or parts is greatly facilitated and subsequentrepaiifor replacement is also correspondingly facilitated.
